SAFETY
SAFETY SUMMARY
Review the following safety precautions to avoid injury and prevent damage to the equipment.
The product should be installed, commissioned, and maintained by qualied and authorized
personnel only.
Install according to installation instructions and comply with all National and Local codes.
Use electrical wire that is sized and rated for the maximum voltage and current of the application.
Properly ground the enclosure to an adequate earth ground.
Observe all terminal and relay contact ratings as called out on the nameplate and in
the installation manual.
Ensure that the enclosure cover is in place and secured tightly during normal operation.
In potentially wet environments thoroughly seal all conduit entries.
If this product is used in a manner not specied by the manufacturer, the safety protection
could be compromised.

BMRX SERIES ROTARY LEVEL INDICATOR
INTRODUCTION
1.0 INTRODUCTION
The BinMaster BMRX is a rotating paddle style level sensor which provides reliable point level
detection for bulk solids, including powder, pellet, and granular materials. The unit has a switch
selectable fail-safe relay that will fall to a "safe" condition in the event of a power failure.
The BMRX motor rotates the drive shaft and paddle at 1 RPM ( 2 RPM on 24 VDC Model). When
the vessel material lls to the level of the indicator paddle, the material causes the paddle to stop
rotating indicating a covered condition. When the material falls away, the paddle starts rotating
again to indicate an uncovered condition.
2.0 INSTALLATION
2.1 Location and Mounting
TOP MOUNT
(For mounting plate options see Figure 4 on page 6)
1. Locate and cut hole in top of bin to t outside diameter
of 1-1/4” pipe coupling (1.950”).
2. Position coupling halfway into bin and weld.
3. Turn unit so conduit opening is in desired location.
4. Add 1/4” extension pipe to desired length with standard 1/4”
coupling on bottom end.
5. Cut 1-1 /4” support pipe approximately 4” shorter than overall
length of 1/4” pipe shaft when used with exible coupling.
6. Insert 1-1/4” pipe into coupling and tighten.
7. Insert paddle into 1/4” coupling and drill holes for lock pins.
SIDE MOUNT
(For mounting plate options see Figure 5 on page 6)
1. Locate and cut hole in side of bin to t outside
diameter of 1-1/4” pipe coupling.
2. Weld on half of standard 1-1/4” pipe coupling to
bin wall ush with inside of bin.
3. Insert hub into coupling and turn until conduit
opening is in blown position.
4. Screw paddle into place and replace lock pin.
5. Shaft and paddle should be shielded in low level
mounting when subjected to material ow.
6. For side mount, a solid coupler is recommended.

MOUNTING PLATES
Mounting plates are necessary when a completely assembled unit is to be mounted on the bin
wall from the outside. A 5-1/2” hole is cut in the bin. Six bolt holes are drilled around the hole to
match the mounting plate. The plate, with the unit attached, is then bolted in place. All mounting
plates are available in carbon and stainless steel.
For use with all rotary
level controls. This
model is used for
top of bin installa-
tions where shaft
extensions and shaft
guards are required.
For use with all
rotary level
controls. This
model is used
primarily for
side of bin
installations.
BMRX Wiring
2.2 Input Power and Field Wiring
The BMRX is available in AC and DC Models. The AC Models are available to be pow-
ered from 24 VAC, 115 VAC, or 230 VAC 50/60 Hz supply voltages. The DC Models are
available to be powered from 12 VDC or 24 VDC supply voltages. See the voltage rating on the
nameplate for the appropriate supply voltage. Field wiring should conform to all national and
local electrical codes and any other agency or authority having jurisdiction over the installation.
For power input, use wire that is sized and rated for the maximum voltage and current as per
equipment ratings and has a temperature rating of at least 70
° C. For relay outputs, use wire
that is sized and rated for the maximum voltage and current as per application, up to 250
VAC 10A, and has a temperature rating of at least 70 ° C. Installation shall be done by
qualied personnel.

Input Power
Power input to the BMRX is connected to the
LINE terminals labelled L and N.
AC Models
On AC models if one of the conductors
is grounded, it should be connected to
the N terminals. The ungrounded conductor
should be connected to the L terminal.
If neither conductor is grounded then one
of them is connected to the N terminal
and the other to the L terminal.
DC Models
On DC models the negative
conductor should be connected to the
N terminal and the positive conductor
should be connected to the L terminal.

2.3 Grounding
An equipment grounding connection (earth ground) must be supplied to the unit for safety.
Connect the ground conductor to the green equipment grounding screw identied in the
enclosure.
3.0 DPDT RELAY
The DPDT relay utilizes a Fail-Safe selector switch. There are 2 positions for this switch, High
(H) and Low (L). A Fail-Safe condition means that the DPDT relay contact positions are set up
so that in the event of a power failure the relay will be de-energized and the contacts will indicate
a condition that is deemed safe for the application.
3.1 Fail-Safe High
Fail-Safe High means that the relay will be energized when the paddle is rotating (uncovered)
and will de-energize when the probe is covered. In this mode, a power failure will cause the
relay contacts to indicate that the paddle is covered, whether it is or not.
3.2 Fail-Safe Low
Fail-Safe Low means that the relay will be de-energized when the paddle is rotating (uncovered)
and will energize when the paddle is covered. In this mode, a power failure will cause the relay
contacts to indicate that the paddle is uncovered whether it is or not.
